Similar in concept to 3D printing, the bike design is perfected using computer-aided design and then constructed by using a powerful laser-sintering process which adds successive, thin layers of the chosen structural material until a solid, fully-formed bike emerges.

But they don't really explain the difference.

Still, it sounds very cool. I wonder how long it will be before it hits production.

I think the difference is that the layers do not necessarily have to be flat. This is definitely interesting, though nylon is a poor material for a bike. Those bearings may look cool, but they must make for horrendous rolling resistance.
